eSIM contains all the data
like a classic SIM card,
but it is much simpler and safer to use.

What is eSIM?

eSIM is a chip that is integrated into your mobile device, so you no longer have to worry about a physical SIM card. eSIM withdraws your profile that stores the data that the operator uses to recognize you as their user. It's easy to use (see our video instructions), and in the future eSIM is expected to completely replace classic SIM cards.

Do you have any further questions?

Go through the most common questions because there might be an answer to your question.

eSIM has the same features as regular physical SIM cards, with the only novelty being the activation QR code. When activating your eSIM, there is no need to enter your PIN, you are only required to scan the activation QR code.

eSIM’s internal memory also allows storage of contacts just like physical SIM cards do; however bear in mind that deleting the eSIM profile from the device also deletes all data stored on the eSIM.

When switching from a physical SIM to an eSIM card, all contacts must be stored on a Google, IOS or similar account.

eSIM is available to A1 Postpaid customers, both private and business, as well as to A1 Prepaid customers using smartphone supporting eSIM card.

You need a mobile device that supports eSIM, and you need an eSIM voucher sold at any A1 store.

If you have lost your mobile device, please report it to the A1 Contact Center available on 077 1234 so we can suspend your line temporarily.

Next, you need to ask for new eSIM voucher at any of our A1 stores.

The new eSIM profile can be activated in the same manner as the initial activation.

All you need to do is to follow the instructions on the eSIM voucher. Next, activate the eSIM in the same way as a regular SIM card, register first and then make your first call.
